STONE LIFTING AND CARRYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 327,989, dated October13, 1885.

Application tiled July 30, 1885. Serial No. 173,107. (No model.)

.To all whom it may concern:

Be it known that I, WILLIAM E. BARBER, of Vyoming, Va-shington county,Rhode Island, have invented certain new and useful Improvements in StoneLifting and Carrying Machines, of which the following is aspecification, reference being had to the accompanying drawings, makingpart hereof.

This improvement is designed to furnish a strong and convenient portablelifting and carrying machine, adapted especially for raising andremoving large stones from farming lands.

My invention includes several novel features tending to the greaterefficiency of the apparatus, which features are hereinafter described,and especially referred to in the appended claims.

In the drawings, Figure l is a perspective view of the machine, showingits prominent points, and Figs. 2 and 3 are details.

The apparatus has two axles, A, mounted on four wheels, B, and apyramidal frame composed of three struts, C, joined at the top by aheavy bolt7 D, and connected about horizontally by two reaches, E. Twoof said struts are secured permanently, by bolts or otherwise, to thehind axle, and the third is, at its foot, pivoted loosely on the forwardaxle by a king-bolt, F. The foot of this strut has an iron shoe7 V,through the bottom of which the king-bolt passes. (See Fig. 3.)

The reaches E are both secured to the forward strut and divergerearwardly to their points of attachment to the other struts, so as toleave an open space for the hoisting-tackle G. A feature of noveltyT isshown in the crossbearns H H, which extend across from one reach to theother each side of the hoistingchains. These beams, either one or both,are pivoted at one end by pins I to one of the reaches having holesformed to receive said pins, and at their other ends the beams havepivotedpawls J, which engage with ratchets K on the other reach, or areotherwise adjustably secured. Aange or plain strip outside of theratchet keeps the pawls in position. The hoistingchain has a cross bar,L, long enough to rest upon the beams H when swung toward each other. Bythese devices the weight may be supported from the reaches instead offrom the/top of the frame, and thus carried more readily with lessswaying on rough ground. The center of'gravity being materially lowered,the line of tension greatly shortened, and strain on the tackle-blocksrelieved, the load is handled with much greater ease and far less strainon the frame than heretofore. The beams H may be perforated to receivepins M, arranged to hold the cross-bar L at either side or centrally,according to the nature of the ground to be passed over. Any desiredkind of hoisting apparatus may be substituted for the simple formillustrated. It is obvious that the cross-bar may be dispensed with byhoisting the stone sufficiently to rest upon and be supported by thebeams H direct.

The reaches E are strengthened and stiffened by oblique braces N fromthe rear axle or struts, and also by spring bars O, of iron or steel,ruiming beneath the reaches and secured by bolts I), passing throughshort slots near the ends of said bars. The purpose of the slotted barsis, while allowing a considerable elasticity to the reaches, to forni anultimate check upon or limit to their downward yielding to prevent theirbeing overstrained and broken. One of the bars, detached, is shown inFig. 2.

I dispense with the usual hounds and swayblocks at the forward axle, andsupport the tongue Q by a chain, R, secured at its upper end between thefront ends of the reaches, beneath the seat S. This construction reducesthe cost, and enables the forward truck to swing entirely around on theking -bolt F without the usual projecting hounds. A foot board, T, isplaced below the seat, and a covered tool-box, U, is provided behind therear axle.

Having thus described my improved stone lifting and carrying machine, Iclaim as my invention- 1. In a portable stone-lifter having suitablehoisting mechanism, the reaches E and the beams H, pivoted at one endthereon, and provided at the other end with a pawl and ratchet orequivalent fastenings, substantially as set forth.

2. The pyramidal frame consisting of the struts C, joined at the apex,connected by the reaches E, and mounted on the wheels and axles B A, incombination with the adjustable IOO 5. The pyramdal frame having itsforward strut mounted on the front axle, and provided 15 with a shoe, V,and king-bolt F, in combination with the tongue Q, and itssupportingchain R, whereby the tongue is supported and may, with theforward truck, be reversed beneath the reaches on the pivot F,substantially 2o as set forth.-
